WINDOW-FRAME.

Specification of Letters Patent.

Patented Sept. 2'2, 191d.

Application fi1ed March 29, 1909. Serial No. 486,332.

To all whom it may concern:

Be it known that I, FRANK E. Fnrsnnn, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful .Vindow-Frame, of which the following is a specification.

The object of my invention is to provide an improved WlDClOW sash and frame so arranged that the sash may be moved up and down in the ordinary way, and, when desired, the window stop of the frame may be moved outwardly into the window frame to thereby permit the sash to be moved either outwardly or inwardly relative to the frame so that it may be reversed in position and the outer surface of the window may be presented to the interior for purposes of cleaning.

More specifically, it is my object to pro vide a device of this kind in which an ordinary window frame may be used, provided with grooves to receive the ordinary parting stops, and my improved parting stops may be applied to the window frame and so arranged that they may easily move in and out of the window frame for the purpose of per mitting the sash to swing inwardly.

A further objeotis to provide improved means for connecting the window sash with the weight-supporting ropesso that the sash may swing on a pivot without removing the ropes from the groove in the frame in which they run.

A further object is to provide improved means for locking the parting stops in their inwardly extended position so that they may not be accidentally moved outwardly.

My invention consists in the construction, arrangement, and combination of the device, whereby the objects contemplated are at tained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure 1 shows a vertical central sectional view through a window frame and two sashes therein provided with my improvements. The dotted lines in said figure show the window sashes in partially reversed po sitions. The dotted lines at the lower portion of the figure indicate that the sash may be moved downwardly when in the position shown by dotted lines. Fig. 2 shows an inside face view of a window frame and two sashes therein embodying my invention. The dotted lines show the positions of the sashes when tilted in the manner shown in Fig. 1. Fig. 3 shows a sectional view on the line 3-3 of Fig. 1. Fig. t shows a sectional view on the line 4:t of Fig. 1. Fig.

5 shows a vertical, central sectional view of a window frame and two sashes therein illustrating a modified form of my invention. The dotted lines therein show the sashes in various positions of their movement. Fig. 6 shows an enlarged, detail, sectional view illustrating the means for connecting the sash with the weight supporting rope used in connection with the modified form of my invention. Fig. 7 shows a similar view of the same parts as shown in Fig. 6 with the upper corner of the sash in position near the bottom of the window frame to show the position the parts assume when the sash is reversed. Fig. 8 shows a detail, horizontal sectional view on the line 88 of Fig. 3. Fig. 9 shows a similar view of the modification taken on the line 99 of Fig. 6. Fig. 10 shows a detail perspective view of the upper end portion of one of the sheet metal casings for the parting stops of my preferred form of the invention. Fig. 11 shows a detail perspective view of one of the upper corners of the steel window frame used in connection with my preferred form of the invention to illustrate the means for locking the parting stops in their inwardly projected positions. Fig. 12 shows a detail view, partly in section, illustrating the means for locking the parting stops in the preferred form of my invention. The dotted lines in said figure show the parting stop unlocked and moved to its outward limit away from the window sash. Fig. 13 shows a detail perspective view illustrating the means for connecting the weight-sup porting rope with the window sash of the preferred form of my invention, and Fig. 14 shows a similar view illustrating the means for connecting the sash with the weight-supporting rope used in connection with the modified form of my invention.

Referring to the accompanying drawings, I have used the reference numeral 10 to indicate the sides of the window frame. In these sides are three longitudinal grooves such as are usually provided in window frames to receive the parting stops, and between the said grooves are the grooves 11 in which the weightsupporting ropes operate. The window sashes, of which there are two, are of the ordinary size and shape and are indicated by the numeral 12. The

sashes are not changed in construction in any way, over the ordinary form, for use in connection with my invention. In each of the grooves in the frame, I provide a casing to receive the parting stop. Each casing comprises a back 13 and parallel sides 1 1, and each casing is open at its inner side. At the top of each of said casings is a rectangular portion 15 which extends up into the top of the window frame for purposes hereinafter made clear. Each of said casings preferably extends to the lower end of the window frame. In each casing, I have mounted a parting stop which is also preferably made of a single piece of sheet metal and comprises a central portion 16 and two sides 17, the latter being designed to enter between the sides of the casing let and to freely move inwardly and outwardly in the casing.

As shown in Figs. a and 8 of the drawings, I connect the parting stop with the casing by means of a series of links 18, each pivoted at one end to a pin 19 in the casing, and, at the other end, to a pin 20 in the parting stop. By this arrangement, it is obvious that when said links are in a substantially horizontal position, as shown in Fig. 4, the parting stops will be at their inner limit of movement, and when the parting stop is moved upwardly and outwardly, the said links will be in a substantially vertical position and the upper end of the parting stop will be contained within the enlarged portion 15 at the top of the casing, and the body portion of the parting stop will be contained wholly within the casing and be flush with the inner surface of the window frame. As shown at the right side of Fig. 8, one side of the parting stop may, if desired, be beveled or inclined, as shown at 21, so that as it moves inwardly, it will wedge against the window sash and thereby force the sash toward the middle parting stop to make a tightjoint between the sash and the two parting stops. Therefore, by placing said parting stop in different positions of its adjustment, the sash may be made tight regardless of the contraction and expansion of the frame and sash.

I have provided for locking all of the parting stops in their inwardly projected position, as shown in Fig. 8, by means of a locking pin 22 which is extended through an opening formed in the window frame and in the sides 14; of the casings. When said pin is inserted, it will engage the outer edges of the parting stops and prevent them from being moved outwardly, and when it is withdrawn, the operator may engage any one or all of the parting stops and move them upwardly and outwardly. I preferably provide a small handle or knob 23 at the top of each parting stop to be grasped by the operator for moving the stop in or out.

Each sash is provided with two counterbalancing weights 2%, sash ropes 25, and pulleys 26 of the ordinary kind arranged in the ordinary manner. I connect these ropes with the sash as follows: In Fig. 13 of the drawings, I have shown a connecting clip comprising a body portion 27 having a short arm 28 pivotally connected with the body portion 27 by the pin 29, and this arm 28 is provided with a cleat 30 to which the sash rope 25 is attached. The said body portion 27 is fixed to the sash and the arm 28 thereof is capable of free up and down movement in the groove 11. The said body portion, however, is designed to stand wholly inside of the inner face of the window frame, as clearly shown in Fig. 8, so that when the parting stops are moved outwardly, the sash will be free to swing within the window frame. However, the part of thesash to which the arm 28 is pivoted cannot move in and out because the arm 28 is retained within the groove 11. By means of this construction, it is obvious that when it is desired to reverse the positions of the sashes, the operator need only remove the pin 22 and then press the parting stops outwardly and upwardly. He may then grasp both sashes and reverse them in position within the window frame, in the manner shown by dotted lines in Fig. 1. Furthermore, it is obvious that the sashes may move up and down in the frame when in any position of their movement so that an operator may have free access to either the inner or outer surfaces of the sashes.

From the foregoing description, it is obvious that the parting stops and their casings are of simple and inexpensive construction, and may be readily, quickly and easily applied to any ordinary window frame, and that the device for connecting the sash ropes with the sashes is also of simple and inex pensive construction and may be quickly and easily applied to ordinary window sashes. So long as the parting stops are in their inwardly extended positions, the sashes may freely move up and down in the ordinary manner. Furthermore, by means of the beveled portion of the inner parting stop, the device may be adjusted to make a tightjoint between the parting stops and the sash, no matter how much contraction or expansion has taken place in the window frame or sash.

The modified form of my invention is intended to be used in connection with window frames made wholly of sheet metal, and in said construction, I form a stationary outer stop 31, a middle casing portion 32, an inner casing portion 33, and two sash rope receiving portions 34, all of which are formed integral of a single piece of sheet metal, as clearly shown in F ig. 9. In the casings and 33, I provide the parting stops 35 similar to the parting stops before described. This form of my invention may be applied to an ordinary frame by inserting the middle and inner casing portions and into the openings of the window frame that receive the common form of window stops. The sash receiving portions rest against the face of the window frame. Ordinary window sashes may be used in my improved window frame. When I use a stationary outer parting stop, it is necessary to provide a sliding connection between the sash supporting rope and the sash, and, for this purpose, I preferably employ the form of device illustrated in Fig. 1 in which the plate 36 is provided to be attached to the sash. This plate has a stationary pin 37. An arm 38 is provided having a transverse slot 39 therein through which the pin 37 is extended, and the rope is attached to the lower end of the arm 38 by means of the clip tO. This arm 38 is arranged to move up and down in the part 34 of the window frame,- and when it is desired to swing the upper sash inwardly to reverse its position, the said slot permits the upper end of the sash to move inwardly far enough so that it may be turned on its pivot and then the upper sash may be reversed in position without moving the outer parting stop. In Fig. 5 of the drawings, the dotted lines which show the position of the upper sash with its upper end near the top of the frame, clearly show the movement of this upper end of the sash when the arm 38 moves relative to the pin 37. Furthermore, by means of this pivoted arm 38, the inner sash may be reversed in position without moving the middle parting stop. This is also illustrated by dotted lines in Fig. 5. In connection with the modified form of my invention, I have also provided improved means for locking the parting stops at their inward limit of movement. This is done by means of a spring arm a1 fixed at its lower end to the upper portion of the parting stop and extended upwardly and having an inwardly extended part T2 at its upper end. This spring arm is provided with a shoulder at 43. Mounted in the parting stop, near its top, is a knob 4L4: capable of up and down movement in the slot 45. The outer end of this knob engages the spring and when the knob is moved upwardly, it will engage the shoulder 43 thereof and thus spring the upper end of the arm 41 outwardly. When the arm 41 is in the posit-ion shown by solid lines in Fig. 12, this upper end portion 42 projects under a stationary part 46 of the window frame. However, when the arm a1 is moved outwardly, then it will be withdrawn from beneath the part &6 and the parting stop may then be swung upwardly and outwardly to the position shown by dotted lines in Fig. 12.

The operation of the modified form of my invention is the same as that before described in connection with the preferred form of my invention, except that in the modified form, each parting stop is independently locked at its inward limit of movement,while in the preferred form, they are all looked together by means of the pin 22. Furthermore, in the modified form, the arm 38 that is connected to the sash rope is permitted to move laterally relative to the sash on account of the slot 39, in addition to its pivotal movement. Furthermore, in the preferred form of the invention, the sash ropes are connected to the central portions of the sashes, while in the modified form they are connected to the upper corners thereof, the latter arrangement being necessary on account of the fact that the outer parting stop in the modified form is stationary.

I claim as my invention.
